Since Pb has no known biological function, elevated levels of Pb in soils and in other natural environments may adversely affect the indigenous biota, including the microbiota. Elevated levels of Pb in soil may also adversely affect microbemediated ecologic processes. There is, however, relatively little information on the mediating influence of the physicochemical factors of the recipient environment on the toxicity of Pb to microbe-mediated ecologic processes. This present study evaluated the influence of the clay minerals, kaolinite and montmorillonite, particulate humic acids, and compost on the degradation of glucose in soil.
